Adobe released security patches for a critical vulnerability (CVE-2026-75650, CVSS 10.0) affecting Adobe Commerce and Magento Open Source, actively exploited since September 4, 2026. The flaw allows arbitrary code execution via PHP code injection in Magento's template system. Affected versions include Adobe Commerce 2.4.9 and earlier, and Magento Open Source 2.4.9 and earlier. Users must apply the VULN-39341 patch and rotate encryption keys. Exploits have deployed a Rust backdoor and PHP web shell.

A zero-day vulnerability, termed StyleSmuggler, has been identified in Adobe Commerce and Magento Open Source, allowing unauthenticated attackers to execute code on affected servers. Security firm Sansec reported that the flaw exploits Magento’s Style properties to bypass security measures. Successful attacks launch a backdoor process, a Rust program that connects to the C2 server at 99.84.67.186, awaiting further commands. The backdoor was not yet weaponized at the time of the report.
